Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, C-clamp or brake caliper tool, torque wrench, brake cleaner, gloves, safety glasses.
Park the vehicle on a flat surface and engage the parking brake.
Loosen the lug nuts slightly while the wheel is still on the ground.

2. Raise the Vehicle

Sub-steps:
1. Use the jack to lift the front or rear of the vehicle (depending on which brake pads are being replaced).
2. Securely place jack stands under the vehicle for safety.
3. Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Caliper

Sub-steps:
1. Locate the caliper mounting bolts and remove them using a socket wrench.
2. Carefully slide the caliper off the rotor. Do not let it hang by the brake line.
3. Support the caliper using a bungee cord or wire to avoid stress on the brake line.

4. Replace the Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Use a C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing.
3. Install the new brake pads into the caliper bracket, ensuring they are seated correctly.

5. Reinstall the Brake Caliper

Sub-steps:
1. Carefully slide the caliper back over the new brake pads.
2. Reinstall and tighten the caliper mounting bolts to the manufacturer’s torque specifications (typically around 79-100 Nm).
3. Ensure all components are secure and aligned properly.

6. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Tighten the lug nuts to the manufacturer’s torque specifications (typically around 110-130 Nm).
4. Pump the brake pedal several times to ensure proper pad seating before driving.
